Method for breeding novel variety of salt-tolerant asparagus

The invention relates to a method for breeding a novel variety of salt-tolerant asparagus, and belongs to the technical field of plant breeding. The method comprises the following steps: planting collected asparagus genetic resources in severe saline-alkali soil with soil salt content of 0.6-0.8 percent by weight, and screening salt-tolerant excellent individual plants; performing hybridization groups by respectively adopting the screened salt-tolerant excellent staminiferous plant and pistillate plant as a male parent and a female parent according the principle that target characters are complementary so as to obtain F1-generation combination; carrying out cross-combination field planting in the saline-alkali soil, and screening out a salt-tolerant, high-yield and high-quality excellent cross-combination; and performing regional trial and production demonstration on the excellent cross-combination so as to breed the novel variety of salt-tolerant asparagus. According to the method, salt-tolerant individual p
